Prospective Evaluation of the Pulse Biosciences nPulse™ Vybrance™ Percutaneous Electrode System in Symptomatic Benign Thyroid Nodules (PRECISE-BTN) Study

The primary objective of this study is to reproduce in a multi-center study results obtained during the feasibility First-In-Human (FIH) study with Prof. Stefano Spiezia, MD (Ospedale del Mare, Naples, Italy) and to monitor additional thyroid-related symptoms and impact of patients quality of life post-ablation using a validated QoL questionnaire.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study design is a prospective, non-randomized, clinical study using the Pulse Biosciences nPulse Vybrance Percutaneous Electrode (PE) System for the treatment of benign thyroid nodules (BTNs) using nanosecond Pulsed Field Ablation (PFA). All participants will receive at least one nsPFA treatment and may be eligible to receive a second treatment at the 6-month follow up visit per physician discretion. All participants will have regularly scheduled ultrasound assessments and administration of questionnaires (e.g., Thy-PRO39 and SF-12) at 1-month, 3 months, 6 months and 12 months post-nsPFA treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Participant is willing and able to provide voluntary, written informed consent to participate in this study and from whom written informed consent has been obtained
  • Participants must be willing and able to comply with study procedures including all follow-up visits
  • Selected nodule is amenable to trans-isthmus approach

  • Nodule is confirmed as benign based on results from one or more of the following diagnostic tests:

    1. (Bethesda II) on at least 2 ultrasound guided fine needle aspirations (FNA) or core needle biopsy (CNB);
    2. A single benign diagnosis of FNA or CNB when the nodule has benign ultrasound features [American College of Radiology (ACR) Thyroid Imaging Reporting & Data System [TI-RAD] TR 1-3, American Thyroid Association [ATA] very low suspicion];
    3. Candidate has a hyperfunctional nodule following 1 ultrasound guided FNA or CNB with or without molecular testing; or

  • Selected nodule is <80.0 ml
  • Participant has normal vocal cord mobility by ultrasound evaluation
  • Participant has presence of compression symptoms, cosmetic concerns or anxiety for which participant requests treatment of the benign thyroid nodule
  • Participant has a solitary thyroid nodule or dominating nodule that is well-defined in multinodular goiter

Exclusion Criteria:

  • Participant has an implantable electronic medical device. (i.e., pacemaker, implantable cardioverter defibrillator)
  • Participant has cystic nodules (< 70% solid components)
  • Participant has calcified nodules

  • Participant has a history of uncontrolled cardiac arrhythmia, uncontrolled hypertension, chronic liver disease or chronic kidney disease (Stage 4-5), or recent history of myocardial infarction or structural heart disease as determined by the Investigator
  • Participant has abnormal contralateral vocal cord function
  • Anesthesia drug allergies
  • Participant is pregnant at the time of screening or within 30 days prior to enrollment
  • Participant has any condition or situation which, in the Investigator's opinion, puts the participant at significant risk, could confound the study results, or may interfere significantly with the participant's participation in the study
  • Use of any investigational device or drug within 30 days prior to enrollment that may confound the results of this study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: nPulse Vybrance Percutaneous Electrode System Treatment Arm
Adult participants who are clinically symptomatic will receive ablation of the benign thyroid nodule using the nPulse Vybrance Percutaneous Electrode System.
Device: nPulse Vybrance Percutaneous Electrode System
The nPulse Vybrance procedure will be performed under ultrasonographic guidance using a local anesthetic at the intended puncture site and all participants will receive general anesthesia in the operating room. The targeted thyroid nodule will be treated within a customized treatment level (DEFAULT) programmed on the Console. The Investigator will treat the entire nodule while protecting from ablation to any surrounding vital structures to prevent serious adverse events throughout the procedure. Any procedural adverse events will be documented, as applicable.

What is the study measuring?

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
